在阅读【A Byte of Python 】（当然是中文版啦）时看到的一句话，很值得思考：
"There are two ways of constructing a software design: one way is to make it so simple that there are obviously no deficiencies; the other is to make it so complicated that there are no obvious deficiencies." -- C. A. R. Hoare
译文：
有两种方式构建软件设计：一种是把软件做得很简单以至于明显找不到缺陷；另一种是把它做得很复杂以至于找不到明显的缺陷。
